[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of agricultural planting, in particular to a method for enriching medium and trace elements in rice bran.
[ background of the invention ]
It is known that 60% of the nutrition essence is concentrated in the rice bran of rice, but the rice bran only accounts for about 10% of the rice, which means that the concentration of some nutrients is 10 times of that of the grains, wherein some nutrients such as oryzanol, inositol, vitamin E, anthocyanin, dietary fiber and the like are mainly concentrated in the rice bran, the content of the rice grains is very low, and the nutrients have unique value. Especially for some important trace elements, the content of the elements in the rice bran can be increased by 100 times by a fertilizing method, for example, the selenium can be increased to 1000 times or even 2000 times of the selenium content of the rice produced under the normal condition, namely, only 1 gram of the rice bran is equivalent to the nutrient content of 1-2 kilograms of the rice, and in addition, the trace nutrients such as zinc, calcium, iron, manganese and the like are similarly concentrated in the rice bran.
[ summary of the invention ]
The invention provides a method for enriching medium and trace elements in rice bran, which can obviously improve the content of the medium and trace elements in the rice bran.
